RAPAPORT... Lucara Diamond Corp. has recovered a 472-carat rough diamond, the
third largest from its Karowe mine in Botswana.

The stone is “top light brown,” meaning it has a relatively
low color grade.

“In 2018, mining at Karowe is focused in the high-value
south lobe, which consistently delivers large, high-quality diamonds in excess
of 10.8 carats in size,” CEO Eira Thomas said last week.

Lucara found the diamond in that part of the mine, the same area that produced the 1,109-carat Lesedi La Rona, which Graff Diamonds purchased for $53 million. The 813-carat Constellation, which sold for a record
$63.1 million, also came
from the Karowe asset.

Lucara will sell the 472-carat diamond at its exceptional-stone tender later this year.
